Let φN , N ≥ 1, be Daubechies’ scaling function with symbol ( 1+e−iξ 2 )N QN (ξ), and let sp(φN ), 0 < p ≤ ∞, be the corresponding Lp Sobolev exponent. In this paper, we make a sharp estimation of sp(φN ), and we prove that there exists a constant C independent of N such that N − ln |QN (2π/3)| ln 2 − C N ≤ sp(φN ) ≤ N − ln |QN (2π/3)| ln 2 . This answers a question of Cohen and Daubeschies (Re...
The influence of physical aging on the β relaxation in La60Ni15Al25 bulk metallic glass has been investigated by mechanical spectroscopy. The amplitude of the β relaxation (ΔG″) decreases while its relaxation time (τ(β)) increases during aging. We find that, as in organic glasses, the changes of ln (τ(β)) and ln (ΔG(max) ) are linearly correlated with ln (τ(β)) = b - a ln (G(max)″). This behavi...
Laminin has been proposed to influence the function of human adrenal cortex. We have studied the distribution of laminin (Ln) chains using immunofluorescence in human fetal and adult adrenal cortex. In the fetal gland Ln alpha2- and alpha5-chains were weakly expressed in the definitive zone, whereas Ln alpha4-, beta1-, and gamma1-chains occurred around vessels. In the adult gland, Ln alpha2-, a...
BACKGROUND AND PURPOSE The need for target adjustment due to respiratory motion variation and the value of carina as a motion surrogate is evaluated for locally advanced non-small-cell lung cancer. MATERIAL AND METHODS Using weekly 4D CTs (with audio-visual biofeedback) of 12 patients, respiratory motion variation of primary tumors (PT), lymph nodes (LN) and carina (C) were determined. RESU...
Three solvothermal systems Ln/As/Se/en, Ln/As/Se/dien and Ln/As/Se/(en+trien) (Ln = lanthanide excluding Pm, en = ethylenediamine, dien = diethylenetriamine, trien = triethylenetetramine) were investigated in detail across the lanthanide series, and ternary lanthanide selenidoarsenates [Ln(en)(3)(H(2)O)(mu-eta(1),eta(1)-AsSe(4))] (Ln = La(1a), Ce(1b), Nd(1c)), [Ln(en)(4)]AsSe(4) x 0.5 en (Ln = ...
We have obtained column density maps for an unbiased sample of 120 molecular clouds in the third quadrant Milky Way mid-plane (b$\le |5|^{\circ}$) within galactic longitude range from 195$^{\circ}$ to 225$^{\circ}$, using high sensitivity $^{12}$CO and $^{13}$CO ($J=1-0$) data Imaging Scroll Painting (MWISP) project. The probability functions hydrogen clouds, N-PDFs, are fitted with both log-no...
BACKGROUND Management of lupus nephritis (LN) would be greatly aided by the discovery of biomarkers that accurately reflect changes in disease activity. Here, we used a proteomics approach to identify potential urinary biomarkers associated with LN. METHODS Urine was obtained from 60 LN patients with paired renal biopsies, 25 active non-LN SLE patients, and 24 healthy controls. Using Luminex,...
The current 7th TNM staging stratifies N1b papillary thyroid cancer (PTC) patients without distant metastasis into either stage I or stage IV merely by an age threshold (45 years). To date, no studies have adequately quantified the mortality risk of PTC patients with N1b disease. We hypothesized that incorporating lymph node (LN) factors into the staging system would better predict cancer-speci...
The retrieved lymph node (LN) count has been validated as a prognostic factor in various cancers. However, the interaction between LN counts and patients' prognosis in gastric cancer with negative-LN metastasis is not fully studied. Surveillance, Epidemiology, and End Results Program (SEER)-registered gastric cancer patients were used for analysis in this study. Patients operated on for gastric...
